That’s the thrust of this month’s opinion, “Deep Groundwater Might Be a Sustainable Solution to the Water Crisis.” Contamination and overuse of shallow groundwater supplies are creating a need for in-depth analysis on the health, safety, and financial concerns associated with accessing deep aquifers.
